1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundSurgical resection is the cornerstone for early-stage non-small cell lung cancer (NSCLC), with lobectomy historically standard. Evolving techniques have spurred debate comparing lobectomy and segmentectomy. This study analyzed early postoperative patient-reported symptoms and functional status in patients with early NSCLC undergoing either procedure.

methodsThis observational cohort study included 248 patients (Lobectomy = 92, Segmentectomy = 156) with early-stage NSCLC (tumor diameter ≤ 2 cm) who underwent uniport video-assisted thoracoscopic surgery (VATS), from December 2021 to December 2023. Patient-reported outcomes were collected using the Perioperative Symptom Assessment for Patients Undergoing Lung Surgery scale at preoperative day 1, daily from postoperative days 1-4, and weekly for postoperative weeks 1-4. We compared early postoperative symptom/functional impairment scores, recovery time from moderate-to-severe symptoms, and short-term clinical outcomes.

resultsBoth groups exhibited comparable early postoperative symptoms and functional status. No significant differences were observed between the two groups in any of the 7 symptom items or the 2 function items (all P > 0.05). The time to recovery from moderate-to-severe symptoms and functional impairment was also similar between the groups. Furthermore, there were no statistically significant differences in short-term clinical outcomes, including operative time, postoperative hospital stays, drainage time, discharge scores, or complication rates (all P > 0.05).

conclusionFor early-stage NSCLC (tumor diameter ≤ 2 cm) undergoing uniport VATS, lobectomy and segmentectomy yield largely similar early postoperative symptom/functional burden, recovery times, and short-term outcomes. Considering external evidence on long-term oncology and function, segmentectomy is supported as a highly suitable option for this patient population.
